\n Center expects a turn toward the north later Sunday, followed by a north-northeastward motion with increasing forward speed Sunday
\n night and Monday. On that forecast track, the center of Hawaii Hurricane Lowell will move across portions of the Papahanaumokuakea
\n Marine National Monument, just west of the main Hawaiian Islands, Monday night.<\/p>\n
\n Hurricane-force winds currently extend outward up to 45 miles from the center, while tropical-storm-force winds reach up to 175
\n miles. The minimum central pressure stands at 943 mb based on aircraft dropsonde data, consistent with a strong Category 3
\n system.<\/p>\n
\n Sunday and Monday. Even with weakening, residents across Kauai County and interests throughout the rest of the Hawaiian Islands
\n should closely monitor advisories, as warnings are likely to be issued later Sunday, according to the NHC advisory<\/a>. The next complete advisory is scheduled
\n for 5:00 AM HST Sunday.<\/p>\n
\n Karina poses no threat to land and is forecast to become a post-tropical low within the next day or two as it passes northeast of
\n the islands.<\/p>\nRainfall, Surge, and Surf Hazards from Hawaii Hurricane Lowell<\/h2>\n
\n island-wide, with isolated maximum totals exceeding 12 inches. This level of rainfall can trigger significant flash flooding and
\n mudslides, especially on Kauai and portions of the Big Island. The Big Island can expect 2 to 6 inches with isolated totals up to 10
\n inches, and Maui faces 2 to 4 inches with isolated maximums up to 8 inches. The remaining islands could see 2 to 4 inches.<\/p>\n
\n vulnerable low-lying coastal zones if the peak surge coincides with high tide. Oahu could see up to 1 foot of surge-related
\n flooding. The deepest surge water is expected along the immediate coast near and to the right of the storm’s center, compounded by
\n large and destructive waves. Swells from Hawaii Hurricane Lowell are also likely to produce life-threatening surf and rip current
\n conditions across many Hawaiian islands over the next several days.<\/p>\n![\"Hawaii](\"https:\/\/ialert.com\/blog\/wp-content\/uploads\/2026\/09\/ialert-hawaii-hurricane-lowell-forecast-cone-watches-september-6-2026.jpg\")
\n watches at 2 AM HST Sunday, September 6, 2026. Yellow marks the Tropical Storm Watch for Kauai and Niihau; the pink line is the
\n Hurricane Watch for Papahanaumokuakea between Nihoa and French Frigate Shoals. Lowell is forecast to pass west of Kauai as a
\n hurricane Monday night and weaken to a tropical storm by Wednesday. Tropical Storm Karina, east of the islands, weakens to a
\n depression by Monday night. Data: NOAA NHC\/CPHC.<\/figcaption><\/figure>\nMeteorologist’s Take<\/h2>\n
\n physically consistent, and the storm retains a substantial wind field even if the peak intensity fluctuates slightly in the short
\n term. The 175-mile radius of tropical-storm-force winds means hazardous conditions can extend well beyond the core, affecting
\n islands that are not directly in the storm’s path.<\/p>\n
\n landfall, still poses serious wind, surge, and rainfall threats to the northwestern end of the island chain, especially Kauai.
\n Orographic enhancement, where moist air is forced upward over mountainous terrain, can concentrate rainfall totals far above the
\n island-wide averages the NHC projects, making flash flooding a primary life-safety concern even though the center is forecast to
\n stay offshore.<\/p>\nHow to Stay Safe During Hawaii Hurricane Lowell<\/h2>\n
\n in coastal or flood-prone areas should follow any evacuation orders issued by local officials without delay. Move to higher ground
\n well ahead of anticipated surge or flood conditions, as flash flooding from 12-inch rainfall totals can develop with little warning
\n on steep island terrain.<\/p>\n
\n assemble a go-bag in case you need to shelter at a designated emergency facility. Avoid streams, drainage channels, and coastal
\n areas during and immediately after the storm, as floodwaters can rise rapidly and rip currents will remain dangerous for several
\n days. Monitor advisories from the National Hurricane Center and your local National Weather Service office frequently, as warnings
\n and watch upgrades are expected later Sunday.<\/p>\nHawaii Hurricane Lowell FAQ<\/h2>\n
